CHURN.

Specification of Letters Patent No. 28,170, dated May 8, 1860.

To all whom it may concern.'

Be it known that I, W. B. GroRnINmn, of Coudersport, in the county of Potter and State of Pennsylvania, have invented a new and useful Improved Pendulum Churn; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l, represents a front elevation vof a churn showing the mechanism for operating the churn and the churn dash. Fig. 2, shows a vertical longitudinal sect-ion taken through the same.

Similar letters of reference indicate corresponding parts in both figures.

The object of this invention is to give a more thorough agitation to the milk contained in the churn box than has heretofore been done, by combining with a swinging motion given to the churn box, a semi-rotary motion of the churn dash, at the same time to effect this with little expenditure of labor and in a very convenient manner.

My invention consists in hanging the churn box, dasher, and dash rod in a swing and operating the swing by means of a treadle so as to give to the churn a pendulum motion, and the dash rod a reciproeating and rotary motion at the same time, as will be hereinafter described.

To enable those skilled in the art to fully understand my invention, I will proceed to describe its construction and operation.

In the drawings, A. represents the base of a frame, proceeding up from each side of which is an upright standard B, both of which are secured together at the top by a cross bar B. Between these two standards is suspended a swing frame C, t-he side arms of which are composed each of two rods between which works the cross head D, of the dash rod D. Each end of this cross bar has a roller on it which allows the bar to be moved up and down freely. Below this head D, and fixed to the bottom board of the swinging frame is the churn box E, which may be of any suitable capacity. The dashrod D', passes up through the middle of the cross head D, and is connected with it by key collars c, that pass through an annular groove a, cut in the dash rod, which connection admits of the rod turning, but gives to it a reciprocating motion when the swing is vibrated, in consequence of the jointed arms F, F, the ends of which are connected to the base A, of the frame, and to each end of the cross-head D.

Gr, is a spiral or twisted strip of metal that is connected to the end of the dash rod D, proceeds up a suitable distance through a plate that is secured to a cross bar H, which bar is fixed to the arms of the swinging frame C, above thel dash rod. The strip G, works up and down through the bar H, partaking of the reciprocating motion of the dash rod D, and gives to the dash rod an alternate rotary motion in consequence of its spiral or screw twist.

On the cross beam from which the swinging arms are suspended is placed (in its middle) a loose grooved pulley J, over which passes a cord K, one end of which is attached to the cross head D, while the other passes down to a treadle L, that is hinged to the base A, of the frame and is fastened to it securely. This treadle is to be operated with the foot so as to operate the machine.

It is intended, in practice, to have two or three annular grooves near the end of the dash-rod, so that the same may be regulated in its motions up and down in the churn box, acccording to the quantity of milk in the churn. The rod can then be adjusted by withdrawing the keys e, e, setting the dash rod to the desired height and again insert ing the keys. These keys should also be withdrawn when it is necesssary to remove the churn from the swinging frame.

From this description it will be seen that the mechanism for operating the churn gives to the parts a combined vibrating, reciprocating, and alternate rotary motion, which are obtained b y simply moving the treadle L. This will thoroughly agitate the contents of the churn box and produce a large amount of butter in a very short time.

Having thus described my invention, what I claim and desire to secure by Letters Pat ent is- The combination with the vibrating frame C, carrying the churn E, of the arms F, F, and spiral plate Gr, cord K, pulley J, and treadle L, all being arranged and operating in the manner and for the purposes herein set forth.
